First , Sikhs are not afraid of Hindus , neither do we hate them . Same goes for muslim - sikh relations.
Its true that Sikhs are neither Hindus nor Muslims . Anyone who does not agree with this , either have skewed view of Sikhism or are ignorant .
I won't say Hindus , in general hate Sikhs .
Both Hindus and Muslims have done nasty things as well as good things to Sikhs .
Hindu Brahmin PM of then , Indira Gandhi ordered military action on Golden Temple . Hindu mobs in Delhi , Haridwar , and other places burnt Sikh Gurudwaras , lit Guru Granth Sahib on fire and danced over it . RSS is another face of Hindus hating Sikhs .
Brahmin Gangu and Suchanand were responsible for martyrdom of younger sons of Guru Gobind Singh ji . Brahman Chandu was responsible for torturing Guru Arjan Dev .
Lakhpat Rai was a mass murderer of Sikhs . He hated Sikhs so much that he even banned the word "Gur" ( jaggery ) because of its similarity in pronunciation to Guru .
But , many Hindus have also been pro-Sikh like
Todar Mal - He did funeral of sons of Guru Gobind Singh by buying land for funeral from Wazir .
and many more .
So , we don't hate anyone because of deed of few.
---- Hindus cannot chant name of Allah , Muslims can't chant Ram . Guru Granth Sahib is only place where on one page Azaan is called out and on on other page Aarti is sung . Such is uniqueness of SGGS
